It might be Rebecca [but I don't think Jessica Capshaw will show up] or Michelle or someone minor important. Other possibility is Angela with Wendell. I don't think it's Bones.But I think we can just guess!

ooooh thats evils...Hmm its not Michelle as her guy is so afraid of Booth he wont be going down below any time in the future.. i dont see Bones or Cam as the test taker... So the money is on Angela or Daisy...

Brennan; We ALL know that is couldn't possibly be Bones especially since she and Booth basically dropped the topic after his surgery. And "jumping the shark" wouldn't even cut that little surprise. Brennan would NEVER go behind Booth's back with his "donation" she has developed emotionally too much for her to rationalize something like that.

Cam: Seeing as Cam doesn't even have a romantic interest and is currently trying to figure out how to raise Michelle, I doubt it would be her. That and the woman has already proclaimed giving up that body isn't worth it. Plus she is not the kind of woman that would have a fling with just anyone and then forget to use some sort of contraceptive.

Angela: I know everybody is probably going to jump on this bandwagon but think about it. Obviously if she got pregnant it would have to be Wendell's. This would irrevocably squash any chance of her and Hodgins getting back together and although sometimes Hart Hanson likes to throw big wrenches into the storyline to shake stuff up i.e. Zack and coma sex, I severely doubt that he would make that kind of mistake. Because we all know that that is exactly what it would be, a HUGE FREAKING MISTAKE! just like Booth and Brennan, Angela and Hodgins are in the "meant to be together no matter what" category.

So my solid vote is for Daisy. It will add a good bonding point for Sweets and Booth, Brennan will be able to observe this, and Daisy will definitely be amazingly hilarious to watch as the story unfolds.

I'm guessing Daisy or Angela - I wouldn't care about Michele - maybe some people would, but she's just not much of a presence in the show for me to care one way or the other and I doubt it is gonna be Bones because Bones would never go behind Booth's back to impregnate herself.

Besides, just the fact that this is even out there as a spoiler seems to indicate it is a secondary character. If it is Angela that will set up a bit of a sticky situation to be sure. I'm going with Daisy.

My guess is Angela. My reasoning behind this is because it takes the pressure of the Booth/Brennan/Baby storyline. And yes Wendell is the likley father but it could be Hodgins, I mean there were some strong sex vibes happening in that last scene of the christmas episode. Just a thought.

At first I thought it was Angela. I don't think it's her after reading all the logic now. We've had some pregnant victims in the past, and the writers don't like repeating themselves (though sometimes they do accidentally.) Brennan... well, you never really know. There could be a romantic interest for her that hasn't been introduced yet. So, I think it's either Brennan or Daisy.

I think that is Angela, but i want i baby for Sweets, ist so cute :D... i remember in s5x01 Angela say that in the dream Brennan is pregnant. I don´t know, I think it would be fun to believe that Brennan Booth is pregnant by him or someone else

i agree olivia... i love a good spoiler... i don't even care who it is, its probably going to be a good episode... at least i hope it is cause its on my birthday. the return of Bones= best present ever :)but i think watching sweets and daisy freak out would be hilarious!

I'm guessing Angela or Daisy, but I would really love for it to be Daisy. That would be a great way for Sweets to have to do a little growing up (or a lot!), and also bring him closer to Booth through bonding over fatherhood.

I'm guessing Daisy. That would be cute and just a little bit creepy. And as Wendy said above a great opportunity for Sweets to grow up and relate to Booth even more. I think it would be just great to see him going to Booth for advice on parenthood.And maybe even a great chance for BB to see Daisy and Sweets holding up a mirror to them. Just a glimpse of what could be.

But in the end it's just some guest star of this episode and not a regular cast member.

Sweets had a fish inside his belly in the dancing promo, may be that is the indicator. And In Cinderella in the cardboard there were two interns in that episode, Wendell as a working intern and Daisy as Sweets girl friend.

I just want to point out that the quote was "When the show returns on Jan. 14, someone must contend with a positive pregnancy TEST." Empasis on test. Pregnanct tests have a margin of error. Espesially on TV where they seem to be about 50/50. I'm not convinced that anyone will actually be pregnant in this episode. If someone is, it might just be a suspect or a victim, but if I had to guess among the main cast. I would say Angela(with Wendell).
